Predicting the Number of Edge-to-Edge Repair Devices Needed to Adequately Treat Mitral Regurgitation Using Transesophageal Echocardiography.
Increased utilization and highly variable costs seen with percutaneous mitral valve edge-to-edge repair have made cost cutting strategies of significant interest. Mitral regurgitation etiology, the number of devices used, and experience all play a role in variability. Currently a paucity of data exists in predicting the number of devices. Any associations found between echocardiography parameters and the number of devices used could help with pre-procedure planning and device placement strategies, ultimately reducing variability and costs. ⋯ The 3D parameters of interest were not associated with the use of multiple devices, but the mitral valve area was associated. Further studies are needed to determine if this relationship is predictive.

Echocardiographic Predictors of Tricuspid Ring Annuloplasty Repair Failure for Functional Tricuspid Regurgitation.
Significant tricuspid regurgitation (TR) recurs after tricuspid valve repair of functional TR in 15% to 20% within the first year, and 30% to 70% within 5 years. Prior investigations report leaflet tethering, and not tricuspid valve annular diameter (TVAD), as predictive of recurrent TR. The authors hypothesize that pre-repair TVAD is predictive of repair failure for functional TR. ⋯ For patients with functional TR undergoing primary left heart surgery, preoperative TVAD (systole and diastole), RV width, and postoperative RV function were predictors of repair outcome. Earlier TV repair and optimizing right heart function may improve repair outcome.

Observational StudyQualitative Assessment of Color M-Mode Signals in the Evaluation of Left Ventricular Diastolic Function: A Proof of Concept Study.
Although the most recent American Society of Echocardiography guidelines are a major step forward in echocardiographic evaluation of diastolic function, the ability to differentiate between normal and abnormal function remains challenging. The authors aimed to determine whether qualitative assessments of color M-mode flow displays could be a useful parameter in the evaluation of left ventricular (LV) diastolic dysfunction. ⋯ Qualitative assessment of color M-mode flow displays offers simple and reliable information of potential usefulness in the evaluation of LV diastolic function.

Inferior Vena Cava Tumor Thrombus Dynamics and Perioperative Pulmonary Embolism: A Single-Center Experience.
To analyze preoperative tumor thrombus progression and occurrence of perioperative pulmonary embolism (PE) in patients with inferior vena cava tumor thrombus resection. ⋯ Perioperative PE was observed in patients with all levels of tumor thrombus. Fifty percent of perioperative PE were observed in patients with infrahepatic tumor thrombus. Post-imaging progression of tumor thrombus was unlikely if the surgery was performed within 3 weeks in patients with levels I or II tumor thrombus or within 1 week in patients with level III tumor thrombus.

Intraoperative Assessment of Coronary Artery Stenosis by 2D Speckle-Tracking Echocardiography: The Correlation Between Peak Strain Rate During Early Diastole and the Severity of Coronary Artery Stenosis in Patients Undergoing Coronary Artery Bypass Grafting.
The effects of inhalation anesthetics on cardiac function and the low correlation between transthoracic and transesophageal echocardiographic measurements may alter the ability of transesophageal echocardiography-derived strain rate during early diastole to detect coronary artery stenosis in anesthetized patients. The authors assessed the correlation between coronary artery stenosis and strain-based parameters during early diastole in heart failure patients with preserved ejection fraction undergoing coronary artery bypass grafting. ⋯ Strain rate during early diastole significantly correlates with the severity of coronary artery stenosis in anesthetized patients suffering from heart failure with preserved ejection fraction.
